Configuring 802.11d Regulatory Domain Support
You can enable or disable IEEE 802.11d Regulatory Domain Support to broadcast the access point
country code information as described below.
Field Description
802.11d
Regulatory
Domain Support
Enabling support for IEEE 802.11d on the access point causes the AP to broadcast
which country it is operating in as a part of its beacons:
To enable 802.11d regulatory domain support, click Enabled.
To disable 802.11d regulatory domain support, click Disabled.
Note: The IEEE 802.11d defines standard rules for the operation of IEEE 802.11
wireless LANs in any country without re-configuration. IEEE 802.11d allows client
stations to operate in any country without re-configuration. The AT-TQ2403
Management Software
must be configured by the Manufacturer via the command
line interface (CLI) country codes for operation in a particular country.
Country Domain Select the country where this device locates.
Note: This item will not appear when AT-TQ2403 is sold to specific regions,

802.11h Regulatory Domain Control
Field Description
IEEE
802.11h
The Administration UI will show whether IEEE 802.11h regulatory domain control is in
effect on the AP. IEEE 802.11h cannot be disabled by an end user Administrator. The
following details are provided for informational purposes only.
IEEE 802.11h is a standard that provides two services required to satisfy certain
regulatory domains for the 5GHz band. These two services are Transmit Power Control
(TPC) and Dynamic Frequency Selection (DFS).
TPC requires that Radio Local Area Net
w
orks (RLANs) operating in the 5 GHz band
use transmitter power control. This involves adhering to a regulatory maximum
transmit output power and a mitigation requirement for each permitted channel. The
result of which is the reduced interference with satellite services.
DFS requires that RLANs operating in the 5 GHz band implement a mechanism to
avoid co-channel operation with radar systems and ensure uniform utilization of any
available channels.
Note: 802.11h is automatically enabled if the AP is configured to work in any country
that requires 802.11h as a minimum standard. This standard is currently only required by
those countries which fall into the European Telecommunications Standard Institute
(ETSI) category. 802.11h is also enabled for Japan.
There are a number of key points for the AP Developer that should be remembered in relation to the
IEEE 802.11h standard:
802.11h only works for the 802.11a band. It is not required for 802.11b, nor 802.11g
